Advancement in technology has paved way for new materials and alloys such as Metal Matrix Composites (MMC) that are not only lightweight but possess higher strength-to-weight ratio and hardness. MMCs find applications ranging from nuclear, and aerospace to defence industries. Due to their uniqueness in terms of wear and high-temperature resistance, In industrial applications, these materials are frequently used. The quality of a machined surface is identified by the measure of surface texture achieved in terms of roughness (Ra). Whereas, the production time depends on the rate of production and is directly related to the material removal rate (Mrr) of a given process. For achieving best outcome, it is very important to address the above two constraints Ra and Mrr. On careful analysis, one can find that these two parameters are contradictory to each other and finding an optimal solution among them is the most crucial task. Conventional machining offers inadequate accuracy and precision while dealing with complicated structures. Also, they are time-consuming and encounter issues while dealing with extremely difficult-to-cut materials. Moreover, localized heating, workpiece stress, and varied cutting forces affect the overall performance of the operation. To address such issues, electrical discharge machining (EDM) offers a controlled electric spark that nearly generates strong cutting force, minimal stress on the workpiece surface during high flexibility and material removal, which has recently gained attention as a technology that is efficient for cutting materials that are challenging to work with. But still, from a techno-economical perspective, achieving higher efficiency is crucial due to the complex-dynamic relationship of the parameters involved in the EDM process. This article deals with the machinability performance and its optimization of Al-SiC alloy while performing machining operations in EDM by considering Pulse on, Wire Feed, Pulse off and Servo voltage as the controlling parameters. The responses considered were Ra, Mrr.
